This standard was first published in 1971 under the title Generic names for man-made fibres . This revision has been taken UP in order to align the standard with the work done at the international level. Wherever the words `International Indian Standard'. Standard' appear. referring to this standard, they should be read as 1 As in the Original Standard, this Page is Intentionally Left Blank IS IS0 6239 : 1991 2076 : 1989 1 Scope 2 General definitions Standard, the following For the purposes of this International This International Standard lists the generic names') used to designate the different categories of man-made fibres at present manufactured on an industrial with the scale for textile and other purposes, together which differentiate them. distinguishing attributes definitions 2.1 apply. name: generic The name given in the first column of table 1, which shall be used to denominate the fibres described in the second column and also fibres which contain not more than 15 % by mass of additives that are fibre-forming. No limit is placed upon the proportion forming. of additives which are not fibre- Chemical difference, which often results in distinctive property differences, is the main basis for the classification in this International Standard: other attributes are used where necessary. The distinguishing attributes are not necessarily those by which the fibres might be identified or the same as those used for naming chemical molecules, nor are they necessarily suitable for the anal-ysis of fibre mixtures. ' fi,bres: from Fibres obtained materials which by a manufacturing occur naturally in 2.2 man-made process, as distinct fibrous form. NOTE The use of the terms "grouo" throughout the text. for example, hydroxyl groups on "linkage" and "unit" has been standardized The generic names are also used to describe textile products (yarns, fabrics, etc.) made from man-made fibres, but it is then accepted that the manufacturing attribute. process may have modified the distinguishing The term "group" acetate. The term "linkage" The term "unit" is used to denote, is used to denote a chemical bond. ic used to denote a repeating unit. t4 In Bo,h thy English and i~nc+, &qg~,ages, the generic names need not he wri?ten with initial capital letters. 3 IS IS0 6239 : 1991 2076 : 1989 3 Generic names Table 1 Generic name 3 .1 cuprol!
